It does screw up the exit code for me; it seems it's because dash is
used as /bin/sh. If I call this shell snippet:
trap "echo trap; exit" 0 1 2 3 9 11 13 15
exit 2
with dash, e.g. "dash foo.sh; echo $?", I get 0, and with bash I get 2.
I'm not sure what POSIX says, but given that calling exit in a trap
handler isn't needed here, I recommend including this as a bug fix.
